BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to 3(5)-amino-pyrazole derivatives, to a process for their preparation, to pharmaceutical compositions containing them, and to their use as therapeutic agents, particularly in the treatment of cancer and cell proliferative disorders.

2. Discussion of the Background

Several cytotoxic drugs such as, e.g., fluorouracil (5-FU), doxorubicin and camptothecins, damage DNA or affect cellular metabolic pathways and thus cause, in many cases, an indirect block of the cell cycle. Therefore, by producing an irreversible damage to both normal and tumor cells, these agents result in a significant toxicity and side-effects.

In this respect, compounds capable of functioning as highly specific antitumor agents by selectively leading to tumor cell arrest and apoptosis, with comparable efficacy but reduced toxicity than the currently available drugs, are desirable.

It is well known that progression through the cell cycle is governed by a series of checkpoint controls, otherwise referred to as restriction points, which are regulated by a family of enzymes known as the cyclin-dependent kinases (cdk). In turn, the cdks themselves are regulated at many levels such as, for instance, binding to cyclins.

The coordinated activation and inactivation of different cyclin/cdk complexes is necessary for normal progression through the cell cycle. Both the critical G1-S and G2-M transitions are controlled by the activation of different cyclin/cdk activities. In G1, both cyclin D/cdk4 and cyclin E/cdk2 are thought to mediate the onset of S-phase. Progression through S-phase requires the activity of cyclin. A/cdk2 whereas the activation of cyclin A/cdc2 (cdk1) a cyclin B/cdc2 are required for the onset of metaphases. For a general reference for cyclins and cyclin-dependent kinases see, for instance, Kevin R. Webster et al, in Exp. Opin. Invest. Drugs, 1998, Vol. 7(6), 865–887.

Checkpoint controls are defective in tumor cells due, in part, to disregulation of cdk activity. For example altered expression of cyclin E and cdks has been observed in tumor cells, and deletion of the cdk inhibitor p27 KIP gene in mice has been shown to result in a higher incidence of cancer.

Increasing evidence supports the idea that the cdks are rate-limiting enzymes in cell cycle progression and, as such, represent molecular targets for therapeutic intervention. In particular, the direct inhibition of cdk/cyclin kinase activity should be helpful in restricting the unregulated proliferation of a tumor cell.

SUMMARY OF THE INVENTION

It is an object of the invention to provide compounds which are useful in treating cell proliferative disorders associated with an altered cell dependent kinase activity. It is another object to provide compounds which have cdk/cyclin kinase inhibitory activity.

It is another object of the invention to provide compounds which are useful in therapy as antitumor agents but lack, in terms of both toxicity and side effects, the drawbacks associated with currently available antitumor drugs discussed above.

The present inventors have now discovered that 3-amino-pyrazoles are endowed with cdk/cyclin kinase inhibitory activity and are thus useful in therapy as antitumor agents and lack, in terms of both toxicity and side effects, the aforementioned drawbacks associated with currently available antitumor drugs.

More specifically, the 3-amino-pyrazoles of the invention are useful in the treatment of a variety of cancers including, but not limited to: carcinoma such as bladder, breast, colon, kidney, liver, lung, including small cell lung cancer, esophagus, gall-bladder, ovary, pancreas, stomach, cervix, thyroid, prostate, and skin, including squamous cell carcinoma; hematopoietic tumors of lymphoid lineage including leukemia, acute lymphocitic leukemia, acute lymphoblastic leukemia, B-cell lymphoma, T-cell-lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, hairy cell lymphoma and Burkett's lymphoma; hematopoietic tumors of myeloid lineage, including acute and chronic myelogenous leukemias, myelodysplastic syndrome and promyelocytic leukemia; tumors of mesenchymal origin, including fibrosarcoma and rhabdomyosarcoma; tumors of the central and peripheral nervous system, including astrocytoma neuroblastoma, glioma and schwannomas; other tumors, including melanoma, seminoma, teratocarcinoma, osteosarcoma, xenoderoma pigmentosum, keratoctanthoma, thyroid follicular cancer and Kaposi's sarcoma.

Due to the key role of cdks in the regulation of cellular proliferation, the 3-amino-pyrazole derivatives are also useful in the treatment of a variety of cell proliferative disorders such as, for example, benign prostate hyperplasia, familial adenomatosis polyposis, neurofibromatosis, psoriasis, vascular smooth cell proliferation associated with atherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis and post-surgical stenosis and restenosis.

The compounds of the invention may be useful in treatment of Alzheimer's disease, as suggested by the fact that cdk5 is involved in the phosphorylation of tau protein (J. Biochem. 117, 741–749, 1995).

The compounds of this invention, as modulators of apoptosis, may also be useful in the treatment of cancer, viral infections, prevention of AIDS development in HIV-infected individuals, autoimmune diseases and neurodegenerative disorders.

The compounds of this invention may be useful in inhibiting tumor angiogenesis and metastasis.

The compounds of the invention may also act as inhibitor of other protein kinases, e.g., protein kinase C, her2, raf1, MEK1, MAP kinase, EGF receptor, PDGF receptor, IGF receptor, PI3 kinase, weel kinase, Src, Ab1, and thus be effective in the treatment of diseases associated with other protein kinases.

The compounds of the invention are also useful in the treatment and prevention of radiotherapy-induced or chemotherapy-induced alopecia.

Accordingly, the present invention provides a method for treating cell proliferative disorders associated with an altered cell dependent kinase activity, by administering to a mammal in need thereof an effective amount of a 3-amino-pyrazole derivative represented by formula (I):

wherein

-   -   R is a C₃–C₆ cycloalkyl group optionally substituted by a         straight or branched C₁–C₆ alkyl or arylalkyl group;     -   R₁ is a straight or branched C₁–C₆ alkyl, C₂–C₄ alkenyl,         cycloalkyl, cycloalkenyl, heterocyclyl, aryl, arylalkyl,         arylcarbonyl, aryloxyalkyl or arylalkenyl group, each of which         may be optionally further substituted;         or a pharmaceutically acceptable salt thereof.

In a preferred embodiment of the method described above, the cell proliferative disorder is selected from the group consisting of cancer, Alzheimer's disease, viral infections, auto-immune diseases and neurodegenerative disorders.

Specific types of cancer that may be treated include carcinoma, squamous cell carcinoma, hematopoietic tumors of myeloid or lymphoid lineage, tumors or mesenchymal origin, tumors of the central and peripheral nervous system, melanoma, seminoma, teratocarcinoma, osteosarcoma, xenoderoma pigmentosum, keratoctanthoma, thyroid follicular cancer, and Kaposi's sarcoma.

In another preferred embodiment of the method described above, the cell proliferative disorder is selected from the group consisting of benign prostate hyperplasia, familial adenomatosis polyposis, neuro-fibromatosis, psoriasis, vascular smooth cell proliferation associated with atherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis and post-surgical stenosis and restenosis.

In addition, the inventive method provides tumor angiogenesis and metastasis inhibition. The inventive method may also provide cell cycle inhibition or cdk/cyclin dependent inhibition.

In addition to the above, the method object of the present invention provides treatment and prevention of radiotherapy-induced or chemotherapy-induced alopecia.

The present invention also provides a 3-amino-pyrazole derivative represented by formula (I):

wherein

-   -   R is a C₃–C₆ cycloalkyl group optionally substituted by a         straight or branched C₁–C₆ alkyl or arylalkyl group;     -   R₁ is a straight or branched C₁–C₆ alkyl, C₂–C₄ alkenyl,         cycloalkyl, cycloalkenyl, heterocyclyl, aryl, arylalkyl,         arylcarbonyl, aryloxyalkyl or arylalkenyl group, each of which         may be optionally further substituted;         or a pharmaceutically acceptable salt thereof.

The present invention also includes methods of synthesizing the 3-amino-pyrazole derivative represented by formula (I). A pharmaceutical composition comprising the 3-amino-pyrazole derivative represented by formula (I) is also included in the present invention.

The present invention also includes a compound useful in the synthesis the 3-amino-pyrazole derivative represented by formula (I), which is represented by formula (V):

wherein R is a C₃–C₆ cycloalkyl group optionally substituted with a straight or branched C₁–C₆ alkyl group.

Pharmacology

The compounds of formula (I) are active as cdk/cyclin inhibitors as they gave positive results when test according to the following procedure.

The inhibiting activity of putative cdk/cyclin inhibitors and the potency of selected compounds was determined through a method of assay based on the use of the MultiScreen-PH 96 well plate (Millipore), in which phosphocellulose filter paper was placed at each well bottom allowing binding of positive charged substrate after a washing/filtration step.

When a radioactivity labelled phosphate moiety was transferred by the ser/threo kinase to the filter-bound histone, light emitted was measured in a scintillation counter.

The inhibition assay of cdk2/Cyclin A activity performed according to the following protocol:

Kinase reaction: 1.5·M histone Hl substrate, 25·M ATP (0.5 uCi P33g-ATP), 100 ng Cyclin A/cdk2 complex, 10·M inhibitor in a final volume of 100·1 buffer (TRIS HCl 10 mM pH 7.5, MgCl2 10 mM, 7.5 mM DTT) were added to each well of a 96 U bottom well plate. After 10 min at 37 C. incubation, reaction was stopped by 20·1 EDTA 120 mM.

Capture: 100·1 were transferred from each well MultiScreen plate, to allow substrate binding phosphocellulose filter. Plates were then washed 3 times with 150·1/well PBS Ca++/Mg++ free and filtered by MultiScreen filtration system.

Detections: filters were allowed to dry at 37° C., then 100·1/well scintillant were added and 33P labelled histone H1 was detected by radioactivity counting in the Top-Count instrument.

Results: data were analyzed and expressed as % inhibition referred to total activity of enzyme (=100%).

All compounds showing inhibition >50% were further analyzed in order to study and define the kinetic-profile of the inhibitor via Ki calculation.

The protocol used was the same described above, except for ATP and substrate concentrations. Either the concentrate of ATP and histone H1 substrate were varied: 4, 8, 12, 24, 48·M for ATP (containing proportionally diluted P33g-ATP) and 0.4, 0.8, 1.2, 2.4, 4.8·M for histone were used in absence and presence of two different, properly chosen inhibitor concentrations.

Experimental data were analyzed by the computer program “SigmaPlot” for Ki determination, using a random bireactant system equation:

$v = \frac{\begin{matrix} {V_{\max}\mspace{34mu}(A)(B)} \\ {\mspace{79mu}{aKAKB}} \end{matrix}}{\begin{matrix} {1 + (A) + (B) + {(A)(B)}} \\ {\mspace{45mu}{{KA}\mspace{31mu}{KB}\mspace{31mu}{aKAKB}}} \end{matrix}}$ where A=ATP and B=histone H1.

In addition, the inhibiting activity of putative cdk/cyclin inhibitors and the potency of selected compounds was determined using a method of assay based on the use of a SPA (Scintillation Proximity Assay) 96 well plate assay. The assay is based on the ability of streptavidin-coated SPA beads to capture a biotinylated peptide derived from a phosphorylation site of histone.

When a radioactivity labelled phosphate moiety was transferred by the ser/threo kinase to the biotinylated histone peptide, light emitted was measured in scintillation counter.

The inhibition assay of cdk5/p25 activity was performed according to the following protocol; Kinase reaction: 1.0·M biotinylated histone peptide substrate, 0.25 uCi P33g-ATP, 4 nM cdk2/p25 complex, 0–100·M] inhibitor in a final volume of 100·1 buffer (Hepes 20 mM pH 7.5, MgCl2 15 mM, 1 mM DTT) were added to each well of a 96 U bottom well plate. After 20 min at 37 C. incubation, the reaction was stopped by the addition of 500 ug SPA beads in phosphate-buffered saline containing 0.1% Triton X-100 50 M ATP and 5 mM EDTA. The beads were allowed to settle, and the radioactivity incorporated in the 33P-labelled peptide was detected in a Top Count scintillation counter.

Results: Data were analyzed and expressed as % Inhibition using the formula: 100×(1−(Unknown−Bkgd)/(Enz. Control−Bkgd))

IC50 values were calculated using a variation of the four parameter logistics equation: Y=100/[1+10^{(LogEC50−X)*Slope}]

Where X=log(uM) and Y=% Inhibition.

Example 2

2-(1,3-benzodioxol-5-yl)-N-(3-cyclopropyl-1H-pyrazol-5-yl)-acetamide

To a solution of 96.8 mg (0.537 mmol) of 2-(1,3-benzodioxol-5-yl)-acetic acid in 3 ml of dichloromethane 360 mg (0.720 mmol) of polystyrene supported dicyclohexylcarbodiimide (loading=2 mmol/g) and 40 mg (0.179 mmol) of tert-butyl-3-amino-5-cyclopropyl-1H-pyrazole-1-carboxylate were added. The mixture was maintained under stirring at room temperature for 96 hours and after that time filtered, washed several times with dichloromethane and evaporated to dryness. The residue was re-dissolved with 3 ml of trifluoroacetic acid 10% V/V in dichloromethane and maintained at room temperature for an hour. The solvent was then evaporated, the residue re-dissolved in dichloromethane and washed with a saturated solution of sodium hydrogenocarbonate. The organic layer was evaporated to dryness to give, after trituration with diethylether, 32 mg (63% yield) of the title compound.

3-Cyclopropyl-3-oxo-propanenitrile

4.5 g (0.15 mol) of sodium hydride 80% were suspended in 200 ml of dioxane, 7.5 ml of acetonitrile (0.15 mol) were dropped and, after 20 minutes, a solution of ethyl cyclopropancarboxylate (0.125 mol) in 100 ml of the same solvent was added. The mixture was maintained at reflux for 3 hours, under stirring, then 400 ml of water were added and the unreacted starting material extracted with methylene chloride. The aqueous layer was acidified with diluted hydrochloric acid and extracted with the same solvent. The organic layer was dried over anhydrous sodium sulfate and evaporated to dryness to give a residue that, after column chromatography (cyclohexane-ethylacetate), afforded 7.8 g (57% yield) of the title compound.

Example 8

N-(3-cyclopropyl-1H-pyrazol-5-yl)benzamide

To a solution of 0.37 g (3 mmol) of 3-cyclopropyl-5-amino-1H-pyrazole in 15 ml of dichloromethane 0.8 ml (7.3 mmol) of N-methylmorpholine and 0.8 ml (6.9 mmol) of benzoyl chloride were successively added at room temperature. After 16 hours under stirring the mixture was concentrated and the residue was dissolved in 15 ml of methanol. 3.5 ml of sodium hydrate 2.5 M were added dropwise and 10 ml of tetrahydrofuran were finally added in order to obtain a homogeneous solution. After 15 minutes the mixture was concentrated and poured into water. The precipitate was filtered and dried in vacuum to afford 585 mg (86% yield) the title compound.

N-(3-cyclopropyl-1H-pyrazol-5-yl)-1H-pyrrole-2-carboxamide

To a solution of 5-amino-3-cyclopropylpyrazole (274 mg, 2.2 mmol) in 6 mL of acetonitrile was added a solution of 2-trichloroacetylpyrrole (430 mg, 2.0 mmol) in 6 mL of acetonitrile, followed by 250 μL of triethylamine. The mixture was stirred and heated at reflux, under nitrogen, for 8 hours. The mixture was poured into ethyl acetate and 1 M KH₂PO₄. The organic phase was dried over Na₂SO₄, concentrated, and the residue taken up in ether. White needles precipitated from ether, whose NMR spectrum revealed a one-to-one complex of the product and ether. The solid was heated to 62° C. under vacuum overnight to afford 190 mg (0.41 mmol, 44%) of ether-free product, m.p. 220–221° C., ¹H NMR (DMSO-d₆) δ 12.1 (s, 1H), 11.5 (s, 1H), 10.2 (s, 1H), 7.06 (s, 1H), 6.89 (s, 1H), 6.24 (s, 1H), 6.08 (s, 1H), 1.86 (m, 1H), 0.89 (m, 2H), 0.66 (m, 2H); IR (drift) 3263 (b), 3174 (b), 2351 (w), 2328 (w), 1906 (w), 1645 (s), 1639 (s), 1587 (s), 1554, 1538, 1488, 1439, 1402, 1319, 786, cm⁻¹ Anal.

Following the same method but employing 5-amino-3-cyclobutylpyrazole, N-(3-cyclobutyl-1H-pyrazol-5-yl)-1H-pyrrole-2-carboxamide, was prepared.

To 260 mg (1.9 mmol) of 5-amino-3-cyclobutylpyrazole in 7 mL of acetonitrile was added 407 mg (1.9 mmol) of 2-trichloroacetylpyrrole and 220 μL of triethylamine. The mixture was stirred and heated at reflux, under nitrogen, for 12 hours. TLC analysis showed some starting material still remained. The mixture was concentrated and chromatographed over silica gel, eluting with 5% methanol in chloroform. The fractions containing the product were concentrated to an oil, which crystallized upon concentration from ether and methanol, to afford 200 mg (0.87 mmol, 46%) of a beige solid, m.p. 207–209° C., ¹H NMR (DMSO-d₆) δ 12.1 (s, 1H), 11.5 (s, 1H), 10.2 (s, 1H), 7.08 (s, 1H), 6.89 (s, 1H), 6.41 (s, 1H), 6.09 (s, 1H), 3.46 (m, 1H), 2.24 (m, 2H), 2.11 (m, 2H), 2.0–1.8 (m, 2H); IR (drift) 3329, 3294, 3257, 3225 (b), 2460 (w), 2351 (w), 2318 (w), 2257 (w), 1643 (s), 1588 (s), 1541, 1487 (s), 1416, 757, 747, cm⁻¹ Anal.
